Body and payload sized to your cargo
Product Description
High-Sided Body on Four Air-Suspended Axles
The steel body is 9,640 mm long, 2,300 mm wide and 1,900 mm deep inside. A 214 x 7,300 hydraulic cylinder at the front raises it and the load runs out through the hinged rear gate. Four 16 t axles, 1,310 mm apart, sit on air springs that even out axle loads as the trailer goes from empty to full and cut road shock to the chassis. The 100 ton class is the upper end of this configuration; the payload you can run is rated per order from cargo density, tractor, axle and tyre ratings and the weight limits on your route.

Air Suspension or Mechanical Suspension for a Dump Trailer?
Three points to decide
Both work on a 4 axle tipper. Choose on your roads, loads and service network.
What should you send us before we size the body?
The Haul Details That Change the Trailer
Send the cargo name, loose bulk density, moisture and particle size; the target load and trips per day; the loading machine, bucket width and drop height; the tractor model and fifth-wheel height; and the destination, route limits and unloading ground. Density sets the body volume, loading impact sets floor and sidewall protection, and the route sets overall size and axle loading.
Configuration options
Axle, Suspension and Brake Options for the 4 Axle Dump Trailer
Air suspension is shown here. Mechanical suspension and other axle brands are available if they suit your roads and service network better.
01FUWA trailer axle
Chinese axle brand; ratings are matched to your payload and axle limits.
02BPW trailer axle
For fleets that keep BPW spares or use BPW service points.
03American-style axle
For markets that run American-style axles and wheel fitments.
04German-style mechanical suspension
Leaf-spring alternative to air suspension, easier to repair at remote sites.
05Suspension spare parts
Springs, hangers and wear parts can ship with the trailer as a spare-parts kit.
06WABCO brake valve
Brake valve option for fleets that standardise on WABCO air-brake parts; ask about ABS.

4 Axle Air Suspension Dump Trailer FAQ
01How much can a 4 axle dump trailer carry?
This configuration is offered in the 100 ton class, but the payload you can run is rated per order from cargo density, tractor, axle and tyre ratings and the weight limits on your route.
02What is the body size?
Inside, 9,640 mm long, 2,300 mm wide and 1,900 mm deep, about 42 cubic metres level-full. Overall the trailer is 10,800 x 2,500 x 3,950 mm.
03Why choose air suspension on a dump trailer?
Air springs share the load across the four axles as it changes and reduce road shock to the chassis. Mechanical suspension is simpler to repair where air-suspension parts are hard to get.
04What axles and tyres are fitted?
Four 16 t axles at 1,310 mm spacing on 13R22.5 tyres.
05How is it unloaded?
A front-mounted 214 x 7,300 hydraulic cylinder raises the body and the load discharges through the hinged rear gate.
06What do you need for a quote?
Cargo type and bulk density, target payload, tractor model, destination country and order quantity.
